  • High power bulk acoustic wave resonator filter devices
    Patent number: 11652469
    Abstract: An acoustic resonator device and method thereof. The device includes a substrate member having an air cavity region. A piezoelectric layer is coupled to and configured overlying the substrate member and the air cavity region. The piezoelectric layer is configured to be characterized by an x-ray rocking curve Full Width at Half Maximum (FWHM) ranging from 0 degrees to 2 degrees. A top electrode is coupled to and configured overlying the piezoelectric layer, while a bottom electrode coupled to and configured underlying the piezoelectric layer within the air cavity region. The configuration of the materials of the piezoelectric layer and the substrate member to achieve the specific FWHM range improves a power handling capability characteristic and a power durability characteristic.
    Type: Grant
